Description

The TE 65 Multiplex Sand/Wheel Abrasion Tester is designed to perform tests according to the conditions described in the following methods:

1. ASTM G65 Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus
2. ASTM G105 Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
3. ASTM B611 Test Method for Abrasive Wear Resistance of Cemented Carbides

The machine is floor standing with test assemblies mounted on a back-plate and abradant discharged downwards into a hopper. Load is applied by pneumatic bellows in conjunction with a manually adjusted precision regulator, with a force transducer for load measurement. Speed set-point control is manual, implemented via a PLC, with input via touch-screen.

Standard Test Configurations

ASTM G65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel.

The other standards have a fluid trough and the slurry is agitated by the wheel rotation. ASTM B611 uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests.
